This invention "relates to window sash construction and particularly window sash-constructions for busses, railway'cars and the like, which sash frames are quickly removable in-cases of emergency, without operating fastening means, by applying a sufficient force to overcome sash retaining devices, or tea window sash'construction which may be called knock-outor kickout sash.

More particularly it has for its object a knockoutgor kick-out, sash in which the sash frame is mounted by a force applied in a direction at a right angle to the sash to overcome the holding action of rigid cams acting inclined plane fashion,

and also a sash which has a slight edgewise movement in one'direction-against 'a restraining resilient or spring action when the force is applied toovercome the holding action of-the cams.

'It further has for its object-a sash frame with a sealing strip extending around the edge of the same to coact "with the window frame to make the sash weather tight, the sealing strip being yieldable when'the sash is being knockedout. The sash is'replaeeable by the reverse of the movements taking-place when 'the sash is being knocked out.

The invention consists in the novel features and in the combination-and constructions hereinafter set forth andclaime'd.

In describing this invention, reference is to the accompanying drawings in which like characters designate corresponding parts in all the views.

Figure -l is an elevation, partly broken away,

of a sash-embodyingthis invention, contiguous portions of the window frame beingalso shown.

Figure 2 is an edge view looking to-the left in Figure l of the sash frame, this being-partly brokenaway and the contiguous'portion of the window'frame being also shown.

Figure 3 is an enlarged fragmentary side perspective projection looking to the left at the upper right-hand corner of-Figure 2.

Figures 4 and 5 are respectively fragmentary face and edge views'of' the lower-rail of the sash circumferent-ially lodged-from the window frame when force is applied to the sash in a-direction at an angle to the plane of the sash frame sufficient to overcome the holding action of thecam means. As here illustrated, the cam means is rigid with'the sash and in order to permit the-cam means to act inclined plane fashion, the entire sash'frame has a shifting movement 'edge wise in one direction against the action of the returning spring also carried by the sash frame.

i designates the sash frame, the stiles and. rails of which are formed'up of sheet metal of the contour shown in Figure 2.

designates Window framing around the window opening in the'car body. The sash frame I is provided with means for supporting glass panes. As here shown, two sub-sashes 3 and 4 are mounted inithe main sash frame, one, as the lower sub-frame 3 being fixed, and the other or upper t beingcapable of being raised and lowered. It is provided with suitable sash locks 5 coacting with racks formed in the upperportions of the uprights or'stiles of the sash frame I. The sub-sash 3 isalso provided with alift handle 8 by which it may be closed, the sash holders ratcheting during the closing movement. The construction of the hub-sashes forms no part of this invention.

9 designates cams on an edge of the sash frame coacting with cams iii on the confronting edge of the window frame, the sash having an edgewise movement due to the cam action in one direction against resilient or spring means on the diametrically opposite edge of the sash frame. In the sash here shown, the sash frame has a shifting movement vertically. The cams 9 are in the form of raised embossments on the edge of the lower rail of the sash frame I, these 00- acting with the complemental cams or embossments it on the sill plate of the window frameZ. When the sash is being placed in position, the embossments Q earn up over the embossments IB and shift the sash edgewise against the action of springs H on the edge of the upper rail of the sash frame, thatis the edge of the sash frame diametrically opposite to the edge on which the cam members are located, these springsxb'ei'ng secured to'the upper rail and having armspressing against the top rail of the window "frame. The opposite of this action takesplace whensu'fificient force is applied 'to'the sash to cause the cams $3 to ride over the cam ii) in dislodging the sash frame from the window frame. The sash frame is placed into position in the window frame by a combined edgewise and pivotal movement,

the upper end of the sash frame I being here shown as held in position by pivots, the parts of which are detachable when the sash I is shifted upwardly by the cams and the sash swung outward. When swung outward, as seen in broken lines Figure 2, the springs may react to shift the sash downward and then the sash swung farther out on its pivotal axis, or the sash may be pushed upward against the springs and completely detached or unhooked from the window frame.

As here shown, the sash frame I is shown as formed with members as hooks l2 formed with slots [3 extending downwardly and open at their lower ends, which slots receive studs 14 on the window frame, the slots being located at the ends of the top rail of the sash frame and the axis of the pivot being parallel to the upper edge of the sash l. The members l2 thus serve to hold the sash at its upper end in the window frame. If desired, the hooks may be omitted and the sash frame I held in position by the cam means on one edge of the sash frame and flanges at the diametrically opposite edge to be first interlocked by holding the sash frame inclined outwardly, and then swinging the sash frame inwardly to allow the cams 9 and if to coaot inclined plane fashion and shift the sash edgewise against the returning springs.

In order to seal the sash frame I in the window frame, or make the sash frame i weather tight, a continuous weather strip I of rubber, or the like, extends circumferentially entirely around the sash frame and extends beyond the edge of the same and wipes at its outer edge on the window frame, it being here shown as seated in a groove i5 opening through the edge of the sash frame. As the sash frame is formed of sheet metal, this groove along the top rail forms a rip for coacting with the sealing strip I! in a channel in the upper rail of the sub-sash l. The stiles are form-ed with a similar groove which forms sash guides for the sub-sash 4. The bottom rail is formed with a similar groove it.

By this construction, a quick, demountable, or knockout sash is provided which is economical to manufacture and readily adapted for safety purposes to the window openings of busses where egress of the passengers is possible in case of accidents and turn-overs where the doors are jammed, or obstructed.
